EMBROIDERY-Hoor.

Application filed October 5, 1912. Serial N10. 724,149.

To all whom t may concern Beit known that I, ARVINE N. THOMAS, a

' citizen of the United States, residing at Oanton, the county of Stark and State of Ohio, have invented a new and useful EmbroideryLHoop, of which the following is a specification. i l

` My invention relates to improvements inV hoops-for holding or supporting cloth or other fabric upon which it is desired to embroiderdesigns vor do similar work, and par ticularly relates to that class of embroidery hoops -wherein an inner, non-adjustable ring and an outer adjustable ring are provided.

' The objects of my invention are to gen erally improve devices; of the character mentioned and to provide a neat, simple, strong, durable and yet easily and cheaply manu-- factured embroidery hoop having a great range of 'adjustment and capable of producing thoroughly satisfactory results.

Theseobjects, together with other objects apparent to those skilled in the art, may be attained by the construction illustrated in thev accompanying drawings, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example.

1n said drawings Figure'l is a perspective view of an embroidery hoop embodying my; Y invention. Fig. 2 1s an enlarged perspective view of a portion of the outer ring including Vthe take-up device. Fig. 3 is a fra.ginentary.`

able'- material andVV is provided externallyY with a shallow groove 2 for the reception of the outer ring.

No claim is herein made for the specific construction of the inner ring and furtherV details thereof need not be set` forth.

rlihe outer ring is composed offri/wire 3 upon which is strung a series of independentlyretatable clamping members e, which are preferablyV of the roundeended cylindrical form illustrated in the drawings. The wire 3 does not entirely encircle the ring 1, but is provided with the spaced terminalA hooks or rings V5 and 6 respectively. The lever and spring housing of the takeup device is formed from a single piece of sheet nieta-l comprising a body 7 formed of a width corresponding to the width of the groove 2 in the inner ring and preferably having a curvature longitudinally adapted to conform to the curvature of said inner ring. Formed integrally with the body 7 are the spaced, parallel outwardly extending tegral lever-fastening lugs 9, which are turned inwardly toward each other, as shown in Fig. 5. Adjacentthe end of the housing where the lugs 9 are located a spring-attaching hook 10 is formed by stamping the same out of the body V7 and bending it upwardly from said body intermediate the flanges 8, as clearly shown in the drawings. One endV of the extensible coiled spring V11 is connected to said hook 10 and the other end of said spring is connected. to the hook 5 of the wire 3, saidspring 11 being somewhat shorter than the distance from the hook 10 to the end ofthe body 7, thus bringing the -endof the Vwire 3 with the firstclamping memberV of the series partially in the end of the housing between the iianges 8, as shown in the drawings.' The take-up lever is likewise formed .from a single piece disposed arms V13 provided adjacent their free lends with alined apertures 1111 in which the lugs 9 of the housing are rotatablyarranged. with an integral wire-fastening lug 15, which is bent over across the space between the arms 13 onthe inner side thereof, said lug 15 being arranged intermediate the two ends ofthe lever.V The wire Srextends bel the lugil, clearly shown in Figs. 2 and 3.

flanges 8 provided at one end with the inof sheet metal and comprisesjthe thumb por-f tion 12 and the integral, spaced, parallelly c '90 One of the arms 13 is provided The apertures 111 and thumb portion 12 are arranged in substantially the same general i outer line of curvature of the'lever, whereas the lug l5, being arranged at the inner edge of the arms 13, is on the inner side of said line of curvature. The take-up lever being connected to the lugs 9, as described, it will be understood that when the thumb portion is moved outwardly and away from the housing, the circumference of the outer ring will be increased by reason of the fact that the lug 15 moves through a circular path into aiposition beyond the end of the housing, whereas, by moving Ythe thumb Yportion from such extended position baclr into a position to overlie the housing, as illustrated in Figs. 1 and 3, the lug 15v will be moved into a position intermediate'the lugs 9 and the hook 10, thusdecreasing the circumference-of the outer ring. As the Vcircumference of the outer ring is thus decreased the end clamping member adjacent they lever is drawn up into position to contact with the end ofI the housing and to protect said clamping member from unduewear, by reason of such contact, a metallic protecting cap 16 is arranged upon the wire 3 andgcov ers the end of said clamping member.'

1t' should be noted that the thumb portion 12eis of'a sufficient width to overlie. the outer edges of the fianges8 when the take-up device is in the closedor contracted position illustrated in Fig. 3 vand the extreme free end of said thumb portion is preferably somewhat narrow and turned down, as

shown at- 17, so as to extend inwardly between the flanges 8, asshown in Figs. 1 and 8, when the deviceV is in the contracted condition. V1t will alsofbenoted, by an inspection of Fig. 3, that when the device is in the contracted'position there will be no tendency for thetake-up lever to move `into the extended position for the reason that thelug 15 lies substantially in line with the wire'3, whereas the lugs 9 are Varranged outwardly beyond the'V wire 3. The very tension of the outer ring will thus Serve to automatically hold the 'take-up device in contracted position until such Ytime it -is desired to free the outer ring fromthe inner, Lwhereupon the f thumbA portion of the'take-up lever maybe readily grasped and said lever moved into the extended position illustrated in Fig. 2.

By means of the construction illustrated `it will be understood that' the'outer ring of my embroidery hoop may be readily clamped uponl cloth or fabric ,of any thickness arranged upon `the inner ring and that, wheny so clamped, t-he spring l1 will afford a certain `resilient vaction making 1t possible to forcibly draw up said cloth or fabric tightly across the innerring,ibut preventing said i fabric from moving as between said outer and inner rings except under intentional effort for that purposey on the part of the operator.

1 claim 1. For an embroidery hoop, in combination withan Outer ring having spaced ends, a take-up device comprising a housing formed from a single piece of sheet metal and comprising a body portion curved to conform to the curvature of the' ring, and spaced fianges extending outwardly from said body, a spring-attaching hook formed on said housing by stamping from the body portion thereof anf integral vtang''extending outwardly between said'flanges, anextensible coil spring Yarranged between said flanges, having one end connected to said hook and the other end connectedto'oneof the ends of said outer ring atone endfof'said housing, a take-up lever formed fromV a single piece of sheet metal and Acomprising a thumb portion and integrahspaced'arms pivotally connected to the flanges of said housing at the other end thereof, Ysaid lever provided with means for the' attachment of the other end of said ring andjsaid other end of said ring extending betweeny said flanges and Varms and connected to saidring connecting means intermediate the ends of said lever, said levervbeing'adapted to pivotally move to throw fsaid thumb portion outwardly and away from said flanges to move said ring attaching means away from said coil spring and to move over toward and down upon said flanges to move said ring attaching ymeans toward said coil spring, whereby to move the spaced ends of said ring away from and toward eachother, andrsaid thumb portion, lwhen" the same engagessaid flanges,"adapted to overlie said spring.
